may concern.-

that I, ALFRED BARTON, of Boston, county of Suffolk, State of, Massach-usetts, have invented an Improvement in Stem Winding and SettingMechanismforWatches, of which the following description, in con-- mention withtheaccompanying drawings, is

a specification, representing like parts.

This invention'relates to stem winding and setting m'echanismsforwatches. One of the objects of this invention is to simplify and improvethe construction and operation of'the'mechanism, and anothorobject of.the invention is to provide .mechan ism, the winding and settingconnection or clutch member of which, when the movement is removedfromithe watch-case, shall-beout of engagementwith the setting traimasdis.

tinguished from any mechanismheretofore constructed in whichthe clutchmember or the movement is out-0t its connection, when case, is inengagement with the setting train.

1' Other featuresot this invention 'will be hereinafter described andset forth in the In the drawings,-Figure1 represents in face view asufficient portion of a watch-case its movement to enable this inventionto be and c constituting a understood; Fig. 2, an enlarged verticalsection of apart of the same taken on the dotted line 23-00; Fig. 3, aview showing the parts in the position they will assume when themovement is removed from the case. Fig. 4:

Fig. 3, showing the clutch p -isa-'s imilar view to member in engagementwith the setting train; and Fig. 5, a modification to be described.

Referring to the drawings, the watch-case A, pendant B, bowO, the crownD with its attached long stem at longitudinally movable within thependant and provided with suitable devices therein to retain it ineither its in or out position, are and maybe of usual or desiredconstruction common to watches of the present time.

The pillar-plate a,-of the watch movement, together with the wheels I),b, constituting a part of the setting train, and the wheels 0, 0 part ofthe winding train, are and may be of usual construction and arrangement;

like letters on the drawings 7 .the' stemis squared, as

and

"lever m having a Mounted in suitable bearings at the under side of thepillar-plate is the longitudinally movable short or inner stern esocketed at its upper end, see Fig. 2, to receive the squared end at ofthe long stem d, said short-stem e at its socketed end being providedwith an enlarged head e, grooved, as at 2 for a pur-.

pose to be described. Near its lower, end at 6?, or otherwise adaptedto'receive the clutch member f which in the present constructionconstitutesthe winding and setting connection, said clutch member beingrotatable with but longitudinally movablewn the said short stem, saidclutch member atitslowe-r end'being toothed as at f or Otherwiseadaptedto engage with and to rotate the wheel I) of .thesetting train, saidclutch member at its opposite or upper end being, in the presentinstance, ratchet toothed to engage the ratchet teeth g on the piniongloosely'journaled upon the short winding traimsaid pinion 9 ,therebyconstituting a parhof the winding train. The pinion g is retained inposition at one side by the bridge pipes a oi the'pillar-platein whichthe short stem e at its opposite side by the winding wheel c with whichit is in mesh. I g

The clutch member f is grooved, as at f to receive the free end of theclutch operating idly secured at "m to the pillar-plate, said operatinglever being T-shaped, and at its uper end socketed to receive therounded-end n of the clutch actuating lever n pivoted at M, and with itsfree endn lying in the groove 6 in the head of the short stem. e.

The resiliency of the tail m of the operat ing lever m tends to movesaid operating lever and the clutch'inember f into its lowermostposition in engagementor mesh with the wheel I) of the setting train,such movement of the operating lever and clutch mem her also actingthrough the actuating lever n to throw the short stem e into itselevated position, such movement of the said short stem, however, beingresisted by the crown D and its longstem 0. within the pendant, theusual devices within the pendant being suiiicient to has one of itsbearings, and v stem 6 and in mesh with the wheel a oi the resilienttail portion m rigz o commonly constructed, when-the watch moveposition.
